Osama - wise or foolish ?

Ronie : Dad, Mom says that had she married Osama-Bin-Laden, she’d have convinced him to avert 9/11.

Dad : I don’t think so, a guy who planned 9/11 so perfectly, would’ve begun his career so foolishly.

Ronie : You’re insulting my Mom.

Dad : No, I am trying to say that after marrying your Mom, he himself would’ve happily flown the plane that hit T’towers.
